Why are my plots looking different when builded at an other computer?

Hi everybody,

I am using the following commands to design my MATLAB plots:

name_str = 'name';
fig = figure('Name',name_str,'NumberTitle','off');
plot(mydata,'LineWidth',2)
grid on
title('title');
legend('legend');
xlabel('label');
ylabel('label');
set(findall(gcf,'type','axes'),'fontsize',30);
set(findall(gcf,'type','text'),'fontSize',30);
set(gca,'LineWidth',2);
set(gca,'color','none');
set(fig,'position',[0 0, 1680 1050]);
set(fig,'PaperPositionMode','Auto'); 
saveas(fig,['G:\Example\Example\','filename'],'epsc');
saveas(fig,['G:\Example\Example\','filename']);

I was hoping, that this code creates always the same style for my figures, but when I use this code at a different computer the figures are getting larger and the fontsize is not the same.

Thank you for your help!
